Sources at Borkowski would not comment when initially approached by PRWeek, but the agency eventually confirmed the acquisition in a statement.

'We have long been envious of Beatwax', said Mark Borkowski. 'They share our values and we are very excited about taking advantage of the obvious creative synergy between the two companies.'

Beatwax MD Michael Brown said: 'Beatwax and Borkowski have identical commitments to bold creative thinking allied to excellence of execution to deliver impressive results for our clients - I think the integration of our skill sets will be a powerful and compelling force in the communications industry.'

It is believed that the acquisition idea began at the recent PRWeek awards, where Borkowski picked up Campaign of the Year for its innovative 'Bring Back Wispa' campaign and Beatwax was shortlisted for its stunt to launch The Simpsons Movie.
